Dear Sir 

May we check with you if customer power module have no S+/S- pin, then UCC39002 also can implement current sharing function?

    Yes it is possible to use UCC39002 to implement current sharing in power supplies that do not have remote-sense pins.#

    In this case, the ADJ pins are used to act directly on the output voltage divider node of each individual power supply, to adjust the Vout of each one to ensure current sharing.

    This app note shows an example of paralleling 2 DC-DC converters without sense pins:

    I hope this helps answer your question.


    Thanks,
